Referring to FIG. 1 , it is a schematic view of a cooling device 100 according to a first embodiment of the present invention.

The cooling device 100 comprises a first cooling portion 10, a second cooling portion 20, and a first receiving cavity S1 sandwiched between the first cooling portion 10 and the second cooling portion 20.

Here, the first receiving cavity S1 is configured to receive a liquid to be cooled, for example, a hot drink, but not limited thereto. The first receiving cavity S1 may be used to receive a solid or a substance in other states.

The first cooling portion 10 is disposed around the second cooling portion 20, and the first cooling portion 10 and the second cooling portion 20 are distributed spaced-apart.

Here, “the first cooling portion 10 is disposed around the second cooling portion 20” means that the first cooling portion 10 is disposed around an entire outer surface of the second cooling portion 20, or the first cooling portion 10 is disposed around partial outer surface of the second cooling portion 20.

“The first cooling portion 10 and the second cooling portion 20 are distributed spaced-apart” means that the first cooling portion 10 and the second cooling portion 20 are cooling portions that work independently, and the two cooling portions are structurally disconnected from each other, or alternatively the two cooling portions are structurally connected via a connection portion, but the connection portion only functions to connect and does not function to transfer a coolant.

It can be seen that in this embodiment, the liquid to be cooled in the first receiving cavity S1 is simultaneously cooled by the first cooling portion 10 and the second cooling portion 20 without an additive being added, so that the cooling effect is substantially improved.

In the present embodiment, the cooling device 100 comprises a cup body 30, the cup body 30 comprises an outer wall 31 and a first inner wall 32 in sequence from the outside to the inside, the first cooling portion 10 is formed between the outer wall 31 and the first inner wall 32, the second cooling portion 20 is located in a cavity S surrounded by the first inner wall 32, and the first receiving cavity S1 is formed between the first inner wall 32 and the second cooling portion 20.

A thickness of the outer wall 31 may be greater than the thickness of the first inner wall 32 to avoid deformation of the cooling device 100, the outer wall 31 may be made of an ABS material, and the first inner wall 32 may be made of a semiconductor material, but not limited thereto.

Specifically, the outer wall 31 comprises an outer bottom wall 311 and an outer peripheral wall 312 disposed around the outer bottom wall 311, the first inner wall 32 comprises a first bottom wall 321 and a first peripheral wall 322 disposed around the first bottom wall 321, a first gap P1 is disposed between the outer bottom wall 311 and the first bottom wall 321, a second gap P2 is disposed between the outer peripheral wall 312 and the first peripheral wall 322, and the first gap P1 is communicated with the second gap P2.

Assuming that the cup body 30 is a cylindrical or conical cup body, at this time, the outer bottom wall 311 and the first bottom wall 321 are both circular, and the outer peripheral wall 312 and the first peripheral wall 322 are both hollow-cylindrical or hollow-conical. That is to say, referring to FIG. 1 , a longitudinal section the first gap P1 and the second gap P2 which are communicated together roughly forms a U shape, and the first cooling portion 10 is formed in the first gap P1 and the second gap P2, whereby an overlapping area of the first cooling portion 10 and the first receiving cavity S1 is increased, thereby improving the cooling effect.

Certainly, in other embodiments, it is also possible that the outer bottom wall 311 and the first bottom wall 321 may be an integral structure, that is, there is no first gap P1 at this time.

In the present embodiment, a gap exists between the outer surface of the second cooling portion 20 and the first bottom wall 321 and between the outer surface of the second cooling portion 20 and the first peripheral wall 322.

That is to say, the second cooling portion 20 is substantially located above the first bottom wall 321, there is a gap between a bottom of the second cooling portion 20 and the first bottom wall 321, and the first peripheral wall 322 is disposed around the second cooling portion 20. In this way, the longitudinal section of the first receiving cavity S1 is U-shaped, and the liquid to be cooled in the first receiving cavity S1 is in full contact with the first cooling portion 10 (or the first inner wall 32) and the second cooling portion 20, thereby further improving the cooling effect.

In the present embodiment, the cooling device 100 further comprises a lid 40 that fits with the cup body 30, and the lid 40 may sealingly fit with the cup body 30, for example, a structure such as a sealing ring may further be disposed between the lid 40 and the cup body 30.

It needs to be appreciated that the cooling device 100 in the present embodiment may be an independent device, the first cooling portion 10 and the second cooling portion 20 may be integrated in the cooling device 100; alternatively, the first cooling portion 10 and the second cooling portion 20 may be disposed independently of the cooling device 100, and the first cooling portion 10 and the second cooling portion 20 are loaded into the cooling device 100 when necessary.

The cooling device 100 may be used in cooperation with a refrigeration device such as a refrigerator. In actual operation, the cooling device 100 with the first cooling portion 10 and the second cooling portion 20 may be first used in cooperation with the refrigerator for refrigeration, so that the first cooling portion 10 and the second cooling portion 20 reserve sufficient cold, and then the cooling device 100 may be used independently, for example, the cooling device 100 may be used for cooling hot drinks outdoors, storing medicines, and the like.

Here, since the first cooling portion 10 and the second cooling portion 20 may reserve enough cold, a refrigeration duration of the cooling device 100 may be prolonged, and the first cooling portion 10 and the second cooling portion 20 may fully cool the liquid to be cooled with a better cooling effect. The cooling device 100 in the present embodiment is structurally simple and convenient to use and provides a good user experience.

Alternatively, the refrigerant may circulate in the first refrigerant circuit 10 by being connected with the first refrigerant circuit 10.

Here, the first receiving cavity S1 having a U-shaped longitudinal section is formed between the second inner wall 33 a and the first inner wall 32 a, and a space enclosed by the second inner wall 33 a is completely filled with a refrigerant to form the second refrigerant circuit 20 a. Reference may be made to the first specific embodiment for the depictions of the refrigerant, and detailed depictions will not be presented any more here.
